Air602 is a 2.4GHz Wi-Fi module based on Winner Micro W600 system-on-chip. Being a new release, it has limited software support. It took me more than a day to make it blink.
Naturally, the next step is to connect a sensor. I decide to reproduce the ESP8266 weather indicator but with Air602 instead.
The Air602 development board, labelled EVB_W602_A11, has six pins:
| Air602 pin | W600 pin |
|---|---|
| IO | PB08 |
| CTS | PB09 |
| RTS | PB10 |
| RX1 | PB11 |
| TX1 | PB12 |
| GND | GND |
I hear there's a new WiFi microcontroller that is cheaper than ESP8266's "unbeatable" low price tag. It is the Air602, a 2.4GHz Wi-Fi module based on Winner Micro W600 system-on-chip.
Currently, Seeed Studio is the only seller for this module. It comes as a bare module for $1.90, or a development board for $2.90. The bare module lacks an antenna and requires surface mount soldering that I'm not comfortable with, so I purchased the development board version that comes with antenna, power regulator, and USB-UART chip.
My order was shipped from Hong Kong, and it took about two months for the order to arrive United States.
